A method and apparatus for monitoring network performance in near real-time by making measurements on packets received at an intermediate node in a wireless communication network. The solution is useful for any packetized communication network that connects a client and application server, and particularly for any application running over TCP/IP protocol. A method is disclosed for measuring end-to-end qualities of a packet-based communication session between a data sender (DS) and a data receiver (DR) at an intermediate node. The measured end-to-end communication qualities may include latency and packet delay variation.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1 wherein the packet-based communication session is a TCP/IP session.
3. The method of claim 1 wherein the DS comprises a UE and the DR comprises a server.
4. The method of claim 1 wherein the forward PD value is calculated as t_2−t_1, and the return PD value is calculated as t_4−t_3.
5. The method of claim 1 wherein the overall PD value measured over a time interval is the variance associated with the forward and return PD measurements during that time interval.
6. The method of claim 1 wherein the DS comprises a UE and the DR comprises a server.
7. The method of claim 1 wherein the DS comprises a server and the DR comprises a UE.
